I am concerned that my firmware may be corrupted or damaged in some way, as my PSP cannot go into sleep mode - it simply shuts off.

The system is already on 6.20 and had CFW installed. I removed the CFW and have the update for 6.20 on the stick, but when I try to install it it errors out saying it is already this version and does not require an update.

You'll further help future posters if you mention your PSP's model - some PSP's use the Pandora + Magic Memory Stick method for flashing, others have to use work-arounds. I personally use Hellcat's Flasher when something goes bonkers in my firmware (I like to experiment. Last time, I replaced the standard web browser with the one provided in Netfront 4 Beta HMM... except that one isn't compatible with Internet Radio, making my Go!Tube installation useless and I had no backup ).

What everyone seems to have missed is that you're trying to update to the same firmware you're on. The UPDATE process is literal....you need to go UP. You're on 6.20 and trying to UPDATE to 6.20 hence the error. You need to go UP to something greater than 6.20.

So you had 6.20 PRO CFW, and you uninstalled it right? Then you are back to 6.20 OFW.

What do you mean you cannot sleep? You only need to flickr the power button, not holding it.

Right. And I mean that I flick the power switch, fastest humanly possible.. the screen goes off, the green light stays on for about 10 seconds, then the unit is idle. I ask it to turn on again, however instead of powering on from a sleeping state, it starts a cold boot, showing the "SONY PSP" boot logo and all, and losing where I was. Let me be clear: I am not holding the power button in any fashion, unless you count the thousandth of a second that a "flick" takes.

How did you uninstall PRO? Removing the files on the memory stick isn't enough, you need to run the pro update and press triangle to uninstall.

What does the system software say in the settings?

You uninstall PRO by re-running the PRO installer, and pressing the Triangle, which it indicates will uninstall the CFW. Then the system will no longer recognize PSP games or homebrew, and in system settings it reads "System Software: Version 6.20"

Right! So, I figure maybe I can update, and use the ChronoSwitch Downgrader again like when I first installed CFW. Question is, what is a safe firmware version to update to, and where should I get it from?
Anyway, that's one idea. I think the main point is trying to find a way to re-flash the OFW, in case there is something wrong with it, as a diagnostic tool. I'm just not 100% sure how to go about it safely right now.

Adapters don't have the same makeup as actual cards, and while they work fine in most cases for normal things (saving and loading data), they tend to fail when it comes to OFW/CFW installs and tweaking. We recommend you use an actual memory stick, at least for anything involving the firmware.

I've installed OFW and CFW several times from an adapter - if the process doesn't require cIPL (on the stick, not the cIPL installer - that works normally ), it should work just fine. I'm guessing he just placed it in the wrong folder.

Installing 6.60 will force you to deal with fast recovery - Perm Patch is only available up to 6.20. A downgrade is a matter of taste then.

Oh, and by the way, isn't 6.60 the latest firmware anyways? If he's now on OFW, can't he just update the normal method built-in method?

I thought OFW was beyond 6.60, but yes thats as far as it goes. I am wondering however if Sony has discontinued the update server, as it keeps giving me an error stating it cannot establish a connection to the server.

PS. I was appalled, APPALLED to find out a PSP 3000 does not support WPA2. Shame Sony, shame!

I also downloaded the official 6.39 update, but same problem saying it is corrupted. Unfortunately I don't have an offical sony memory stick at the moment.
